Quincy Air Compressor 30 HP 132 Gallon Rotary Screw with Dryer 3 Phase

The Quincy QGS rotary screw compressor, part number 4152026545, is designed for demanding shop environments where motor protection matters as much as continuous air production. Its TEFC electric motor with IP55 wash-down protection helps shield against dust and low-pressure water from any direction, making this configuration particularly useful where compressors share air with sanding, welding, washing, milling, or other debris- and moisture-producing work. The package combines a 100% duty-cycle oil-injected twin-screw airend, 132-gallon horizontal receiver, integrated refrigerated air dryer, and aftercooler on a single skid. Note: the unit measures 74" × 30.7" × 72.2" and weighs 1,365 lbs.

The 100% duty-cycle screw airend is built for continuous operation rather than scheduled cool-down periods. Premium synthetic lubrication supports long service intervals and low oil carryover, while constant fluid monitoring, a spin-on filter, and low-oil shutdown help protect the compressor during extended use. The full sound enclosure reduces the noise associated with continuous operation, while the integrated refrigerated dryer removes moisture from the compressed-air system. The Infologic2 Basic controller provides programmable auto-restart and remote start/stop, and it can network up to six compatible compressors, giving growing facilities a way to add capacity under coordinated control. The display also provides pressure, temperature, dewpoint, and alarm information.

This configuration is particularly well suited to body shops, paint operations, fabrication facilities, woodshops, grain-handling environments, and other dusty or damp workplaces. It also makes sense for shops that want a complete compressor, receiver, and dryer package delivered as one system rather than assembling separate components. The horizontal design creates a long, relatively narrow footprint that can work well along a wall. Electrical service must be 208–230/460V three-phase, and Quincy does not publish a universal amp or breaker requirement, so a certified electrician should size the installation from the machine's nameplate.

Will It Fit? Siting and Power

Footprint. The package measures 74" long, 30.7" wide, and 72.2" tall, with a weight of 1,365 lbs. The horizontal receiver gives the package a long, narrow footprint that generally works better along a wall than as a floor island. It still requires a level installation surface and sufficient clearance to open the hinged doors and remove the service panels — access that is essential for routine maintenance.

Electrical. The motor is specified for 208–230/460V, three-phase power. Quincy does not publish an amp draw or recommended breaker size for this configuration; the specification directs customers to consult a certified electrician. We are not going to substitute an estimate for a manufacturer specification. Your electrician should use the machine's nameplate to determine the appropriate feeder and overcurrent protection. Arrange that evaluation before delivery is scheduled.

Air Outlet and Plumbing. The receiver outlet is 1", providing the connection point for the shop's main air line. Plan the drop, isolation valve, and condensate-drain access before installation. The electronic drain valve is listed as not included with this configuration, so condensate from the receiver will require manual draining or a separately installed drain solution.

Confirming that the installation area, floor, electrical supply, ventilation, and drainage are suitable for a compressor designed for continuous operation is the customer's responsibility. It is considerably easier to resolve those requirements before the crate arrives.

What IP55 Wash-Down Protection Actually Means

The IP55-rated TEFC motor is designed to provide protection against dust ingress and water projected by jets from any direction. That can be valuable in demanding shop environments where airborne debris or occasional water exposure is part of the working environment.

However, IP55 should not be treated as a guarantee against every type of contamination or exposure. Proper ventilation, installation, and routine maintenance still matter. If the compressor shares its environment with sanding, welding, washing, or machining operations, the motor's enclosed, protected design provides an additional layer of protection compared with a less-protected motor configuration.

Continuous Duty and the Control That Goes With It

The airend uses an oil-injected twin-screw design rated for 100% duty cycle, meaning it is designed for continuous operation rather than requiring scheduled cool-down periods like a duty-limited reciprocating compressor.

Premium synthetic lubrication is specified for extended service intervals, while oil separation and filtration help minimize oil carryover into the compressed-air system. The system also includes fluid monitoring and a spin-on fluid filter to support routine maintenance.

The rotary screw airend's continuous compression, combined with the full sound enclosure, also produces a smoother operating profile than a reciprocating piston compressor. The quieter operation comes from the compressor's design and enclosure rather than from a single isolated component.

The Infologic2 Basic microprocessor controller manages start/stop functions, programmable auto-restart, and remote start/stop. It can also network up to six compressors, allowing additional capacity to be integrated into the control system later.

The display provides operating information including auto-run and alarm status, along with pressure and temperature readings. Where a refrigerated air dryer is included in the specific configuration, the available dryer information can also be used to monitor its operating status.

Perfect For

• Body shops and paint operations. The protected TEFC motor and integrated refrigerated air dryer make this configuration well suited to applications where air quality and reliable operation matter.
• Woodshops and fabrication environments. The enclosed, IP55-rated motor provides additional protection in areas where airborne dust or occasional water exposure is present.
• Shops wanting one integrated package. The compressor, receiver, and integrated dryer arrive together on a single skid.
• Operations planning for future expansion. The controller can network up to six compressors, providing a path for additional capacity.

What's in the Box

Quincy lists this package as the QGS rotary screw compressor with Infologic2 Basic controller and display panel, TEFC electric motor with IP55 protection, integrated refrigerated air dryer, and 132-gallon horizontal receiver.

The package also includes an aftercooler, oil sight glass, pressure gauge, air filter, and low-oil shutdown protection. An electronic drain valve is listed as not included.

Specifications

Certification, Stated Honestly

The specification sheet records an ASME certification for this unit, which applies to the 132-gallon receiver included in this tank-mounted package. That certification covers the pressure vessel itself; it should not be interpreted as certification of the packaged compressor's electrical system, controls, or overall equipment assembly.

Beyond the ASME certification, our product data does not record an independent third-party electrical or equipment safety listing for the packaged machine as a whole. We are not going to imply that one exists.

If your jurisdiction, insurer, or corporate engineering standards require a specific independent third-party listing for permanently installed equipment, confirm the requirement before purchasing and installation rather than discovering it during an inspection. If needed, ask us for the available manufacturer documentation so you can verify the unit's compliance in advance.

Shipping and Delivery

Freight only within the lower 48 states, with shipping priced live at checkout based on the delivery address you provide.

At 1,365 lbs on a long skid, this shipment requires an appropriate unloading method. Plan for a loading dock, forklift, or other suitable equipment at the delivery location, or arrange pickup from the carrier's terminal if that is more practical.

Residential delivery may carry an additional residential fee, which will be shown at checkout when applicable.

Inspect the shipment before signing for delivery. Examine the crate and accessible components for visible damage, take photographs, and have any damage documented on the bill of lading before accepting the shipment. Once a shipment has been signed for without notation, resolving a freight-damage claim can become significantly more difficult.

Warranty

Published standard warranty coverage for this unit is 1 year for consumer use and 1 year for commercial use. An extended 3-year factory warranty is available, while the True Blue 5-year warranty applies when the machine is commissioned through a Quincy-authorized start-up, subject to the applicable warranty terms and conditions.

The authorized start-up requirement is important if the 5-year coverage is your goal. Arrange the required commissioning before the compressor is placed into service rather than assuming the extended coverage can be added afterward.

For any potential warranty issue, contact us before opening or disassembling the airend, dryer circuit, or motor. Unauthorized disassembly can complicate the warranty assessment and make it more difficult to establish the cause of a failure.

Keep the commissioning documentation and maintenance records together, including fluid and filter service history. These records can be important when documenting proper maintenance and evaluating a warranty claim.
